What Is Biotin and Why Is It Important?

If you're interested in maintaining healthy hair, skin and nails, you've likely come across biotin.

While deficiency is rare in healthy people, supplementation can be beneficial for those with inadequate intake or specific health goals. This 21st Century Biotin 5000 mcg capsule provides a high-strength dose for convenient daily supplementation.
